Emma Watson admitted her split with ex Matt Janney was "horrendous" and fans got excited when they saw her with a new mystery man in Los Angeles recently.

It's now been revealed the 25-year-old actress was hanging out with Roberto Aguire, who she first met while filming Harry Potter and the Goblet of Fire, and we're hoping their long-term friendship could turn into a romance!

Roberto, 27, previously spoke about their close relationship in 2012, telling JustJared: "I was doing an internship in the special effects department at the time.

"And one day we had a chance encounter that led to us spending half a day together exchanging stories and dance moves. We never really lost touch after that and now she's one of my best friends." Naww.

Roberto, an actor and director, is originally from Mexico, grew up mostly in Switzerland, and lived in Los Angeles. Pretty impressive. So, he's hot, multi-talented and well-travelled.

He was spotted with Emma having a cosy lunch in Los Feliz, California on October 4 and the pair looked pretty cute together. They'd make a great couple.

Emma split from the rugby player in December following a year together and The Bling Ring star fled to Canada's Rocky Mountains shortly before it fell apart to stay at a facility which enforces a week-long vow of silence.

She said: "I felt really uncomfortable, even before my relationship ended, I went on a silent retreat, because I really wanted to figure out how to be at home with myself."

Talking about her past relationships, she also told the September issue of UK Vogue magazine: "The boyfriends or partners I've had have generally made me feel really cherished. They've built me up.

"I certainly haven't found that with doing all that I do or being all that I am, that I've struggled in my love life. I just think it's very patronising towards men. It undermines them."
